Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514716, here are decompositions:

29 + 31514687 = 31514716
53 + 31514663 = 31514716
89 + 31514627 = 31514716
137 + 31514579 = 31514716
179 + 31514537 = 31514716
239 + 31514477 = 31514716
293 + 31514423 = 31514716
419 + 31514297 = 31514716

Showing the first eight; more decompositions exist.
